I want to read a folder that contains large number of tif files. (say 1000 tif images) requirement is to read all files and store in a array/array pointer.
I have a dialog window with a CTabCtrl. The following code is successful in showing an icon along with the text name on each of 16 tabs. The icons are 16x16 pixel squares, 4-bit, that I made with Visual Studio 2008's resource editor.
The icons to have transparent pixels (the first pixel of the color map), so that I can "shape" them to be circles, etc., instead of squares.
However, the transparency works ONLY IF I use ILC_COLOR8 instead of ILC_COLOR4, and use LR_LOADMAP3DCOLORS. (Neither of these are documented as being related.) If I don't have LR_LOADMAP3DCOLORS, or if I use ILC_COLOR4, the "transparent" parts of the icon are colored white instead.
My code now works....
// Configure the Tab control. CTabCtrl* ptab = (CTabCtrl*) GetDlgItem( IDC_TAB1 ); static CImageList* pil = NULL; if ( ! pil ) { pil = new CImageList;
I want to make a launcher for my program but the installation folder is different from one computer to another so I need a function or something that shows the path of the executable file.how to import a file from another folder.
#include<stdio.h> int main(void) { FILE *fp; *fp=fopen("C:Documents and Settings...something.txt","r"); }
Basically, this function purpose is to make a backup of source in folder every X minutes (depending on user's input).
The problem is the second call to open():
This call attempts to open the file for writing, and creates it if it is not already exist.
It also truncates it before writing to it - and that's my concern:
Let's say this is the second time this function runs, so copy is already exist. open() will then truncate it, and then one of the system calls in the while loop fails.
In this situation, I might be left with no backup file.
The problem also arises for when source is a read-only file:
If source is a read-only file, and copy is not already exist (meaning - it's the first backup attempt), then everything's fine, but, if source is a read-only file and copy is already exist, then I have to first remove copy altogather, and make a fresh copy of source.
Making a backup with new name for copy every time copy_file() runs, will solve this problem, and how can this be accomplished?
I should say that I'd really prefer that copy and source will have the same names when copy_file() returns...
#include <iostream> using std::cout; using std::endl; int main(int argc, char* argv[])
[Code] ...
The only Problem I have is that I need to know how to open a command window at the folder containing the .exe file(this program), inorder to enter the program name or arguments.
I want to delete the folder from the file system, but I am getting error of access permission.
I want to change the permission of the folder so my program can delete it.
The problem I am facing on google search is I am getting results mostly for MFC code which is windows specific. However, I want to write a code in core C++ that works on all platforms like unix and windows.
I am trying to save the excel file in D:/newfolder. but the file saving as newfolderFilename. The newfolder is already created in D drive. File save path i am getting from textbox ....
The goal is to change the status bar (CMFCRibbonStatusBar) icons based on some events. (The old CMFCStatusBar class had the SetPaneIcon() member that easily solves the problem.)
The "improved" CMFCRibbonStatusBarPane has no members to set the icon, other then the constructor. Being a subclass of CMFCRibbonButton, it has SetImageIndex() that sets the icon index in the image list. The MS online support does not mention how and where to set that "list of images". My understanding is that the list belongs to the Button's parent; in this case it is the CMFCRibbonStatusBar, which has no methods to set any image list. How and where am I supposed to set that list of images for the status bar?
Second related question: I have tried to set the pane icon with the CMFCRibbonStatusBarPane() constructor by loading it from an icon resource. The icon appears shortly and then it is replaced by a gray patch. (for tests I also used one of the icons given by the MFC wizard, with the same result)
The code is:
int CMainFrame::OnCreate(LPCREATESTRUCT lpCreateStruct) { .......... if (!m_wndStatusBar.Create(this)) { TRACE0("Failed to create status bar ");
[Code] ....
This code was placed within a program created by the MFC wizard that does nothing else. I absolutely do not "touch" the status bar after it is created here in CMainFrame::OnCreate().
Apparently the icon is "erased" after OnCreate() exits. Where, how? I have made HICON icon; a member of my CMainFrame class, with the same result.
am trying to create a service that will try to create a service that will monitor a folder. Whenever a new file gets created, I am trying to read the contents of new file and copy contents (with same file) at a new location.
The problem I am facing is that only first file that gets its name copied and a file created at a new location, but without any contents. The subsequent files do not get created at all.
My Services.cs looks like this:-
public partial class Service1 : ServiceBase { public Service1() {
I need to parse the file in such a way that I can create a filesystem hierarchy as if I were enumerating files/directories. Ultimately I want to add these to a tree gui control with everything under its proper node without duplicating anything. It should look roughly like so:
dir -file -dir -file -dir -file
I can open the file and add nodes/children to the tree control but how should I go about doing the actual parsing? How can I find a filename and say "this belongs under this node"? I want to do this efficient as possible even if I must use multiple threads.
I have a specific byte (that is unsigned char) array, that I need to find in a very big file (2GB or so), currently I'm using:
size_t fsFind(FILE* device, byte* data, size_t size) { int SIZE = (1024 > size) ? 1024 : size; byte buffer[SIZE]; int pos = 0; int loc = ftell(device);
[Code] ....
Which seems to find proper result on first use, but on subsequent searches it seems to find invalid positions, is there something I'm doing wrong, or is there a better way?
I have a large binary file (84GB) that needs to be broken down into smaller file sizes (~1GB to 8GB) for analysis. The binary file is on a 32-bit machine and cannot be copied to another machine for analysis. The PC has Visual Studio 6.0 and is not upgradable. My issue is I'm using the following generic code to create the smaller files.
fseek(file, start, SEEK_SET); end = start + (variable based on file size); fseek(file, end, SEEK_SET); for (i=start; i<end; i++) { if(!feof(f)) { byte = fgetc(f); fputc(byte,new_file); } }
However, on a 32-bit machine, the iterator can only count up to ~2billion. Which means that I'm unable to copy anything past ~2GB. My original idea was to delete from the large binary file as I read from it so that I can reset the iterator on every read. However, I haven't come across a way to delete binary file entries.
Is there any other way that to break down a large binary file into smaller units? Or is there a way to delete binary file entries in sections or per entry?
On a 64-bit machine I could use _fseeki64. I've been reading that some versions of Visual 6.0 are capable of supporting 64-bit numbers but when using _fseeki64 or _lseeki64 on this machine its an "undeclared identifier"
I am currently working out on a problem in which a c program is to be made which shows a large text file in parts. f For example: If file contains 200 lines. 50 lines will be shown on first page and user is asked to press any key to move to next page until EOF is found. user is allowed to return to previous page as well, and this is very complicated task for me. I tried to move cursor to a specific position using fseek etc but it page doesn't stop and reaches to end quickly.
Im trying to read and store several students information so that i can have an options menu where i can enter a student number and the program prints all the information stored about that student. The way i have it set up now, doesn't work for this because all info is reinitialized to stud1. Is there another way to store this info other than defining stud1, stud2,.....,stud200?
I had wanted to make a program that will tell someone how many files there are in a folder and its subfolders with a certain extension. I am not sure how to find the files.
I am using dir object from dirent.h to read files of a folder. The code I am using in order to read all data is the following:
vector<string> directories;
DIR *pDIR; const char * c = path.c_str(); struct dirent *entry;
[Code]....
I am wandering when I am trying to read two times the files of the same folder, it will be stored with the same order or every time I ll read in folder it ll return different file order?
I want to rename all files in a folder (exactly I want to change extension file example:"FILE0001.CHK" to (FILE0001.JPG)), i know rename function , but how to use it all files, files names going sequencely (FILE0001.CHK,FILE002.CHK until FILE3000.CHK) ... How i can rename or change extension file quickly and easily.
